immune system
abnormal pro-B cell morphology ( J:134528 )
• two weeks after Cre induction by pI-pC injection, the ratio of BP-1+HAShigh cells to BP-1+HASlow cells is much lower than in controls indicating a defect in the transition from pro-B cells to pre-B cells
• there is a 6-fold reduction in the percentage of pro B cells in the bone marrow that are in the S phase
abnormal pro-B cell differentiation ( J:134528 )
• bone marrow from mutant mice that have had induction of Cre by pI-pC injection are unable to reconstitute the B cell compartment in irradiated alymphoid mice
• reconstitution still fails when pro B cells are encouraged to differentiate by injection of Igbeta antibodies into the host mice
decreased pre-B cell number ( J:134528 )
• two weeks after Cre induction by pI-pC injection, pre-B cell (B220lowIgM-Cd43-) numbers in the bone marrow are 7% of controls
• immature B cells (B220lowIgM+Cd43-) in the bone marrow are also reduced by a similar amount
